Known issues

We are aware of the following issues using Anaconda Enterprise. If you’re experiencing other unexpected behavior, consider checking our Support Knowledge Base.

Unable to obtain Zeppelin credentials

After selecting Credential and clicking the question mark icon in the Zeppelin editor, the user should be redirected to Zeppelin documentation explaining the process for obtaining credentials. However, that link is broken.


Rather than committing something sensitive in your code/repository through Zeppelin, create a Kubernetes secret in JSON format.

Process for installing the Anaconda Enterprise CLI doesn’t work

The process of installing the Anaconda Enterprise CLI downgrades packages that are essential to the AE CLI, resulting in a conda env that won’t work with the tool.


Follow this process to create a working conda environment, and activate it:

conda create -n cli-test -c anaconda-enterprise-cli git python=3.6 cas-mirror

conda activate cli-test

To access help for using the Anaconda Enterprise CLI, run anaconda-enterprise-cli --help.

Attempting to install new PyViz packages in JupyterLab results in error

The new PyViz libraries aren’t compatible with the version of JupyterLab used in Anaconda Enterprise. For more information on PyViz compatibility, see


Open the project in Jupyter Notebook.

Unable to download files when running JupyterLab in Chrome browser

If you attempt to download a file from within a JupyterLab project running on Chrome, you may see a Failed/Forbidden error, preventing you from being unable to download the file.


Open the project in Jupyter Notebook or another supported browser, such as Firefox or Safari, and download the file.

Unexpected metadata in a package breaks AE channel

The cspice and spiceypy packages mirrored from conda-forge include incompatible metadata, which causes a channeldata.json build failure, and makes the entire channel inaccessible.


Remove these packages from the AE channel, or update your conda-forge mirror to pull in the latest packages.

Custom conda configuration file may be overwritten

If you add a custom .condarc file to your project using the anaconda-enterprise-cli spark-config command, it may get overwritten with the default config options when you deploy the project.


Place the .condarc file in a directory other than your home directory (/opt/continuum/.condarc).

Note that the conda config settings are loaded from all of the files on the conda config search path. The config settings are merged together, with keys from higher priority files taking precedence over keys from lower priority files. If you need extra settings, start by adding the .condarc file to a lower priority file first and see if this works for you.

For more information on how directory locations are prioritized, see this blog post.

Starting in Anaconda Enterprise 5.3.1, you can also set global config variables via a config map, as an alternative to using the AE CLI.

Incorrect information in command output

When running the anaconda-enterprise-cli spark-config command to connect to a remote Hadoop Spark cluster from within a project, the output says you need to specify the namespace by including -n anaconda-enterprise.


You must omit -n anaconda-enterprise from the command, as AE is installed in the default namespace.

Error creating an environment immediately after installation

At least one project must exist on the platform before you can create an environment. If you attempt to create an environment first, the logs will say that the associated job is running, and the container isn’t ready.


Create a project first. The environment creation process will continue and successfully complete after a few minutes.

Cluster performance may degrade after extended use

The default limit for max_user_watches may be insufficient, and can be increased to improve cluster longevity.


Run the following command on each node in the cluster, to help the cluster remain active:

sysctl -w fs.inotify.max_user_watches=1048576

To ensure this change persists across reboots, you’ll also need to run the following command:

sudo echo -e "fs.inotify.max_user_watches = 1048576" > /etc/sysctl.d/10-fs.inotify.max_user_watches.conf

Invalid issuer URL causes library to get stuck in a sync loop

When using the Anaconda Enterprise Operations Center to create an OIDC Auth Connector, if you enter an invalid issuer url in the spec, the go-oidc library can get stuck in a sync loop. This will affect all connectors.


On a single node cluster, you’ll need to do the following shut down gravity:

  1. Find the gravity services: systemctl list-units | grep gravity.

    You will see output like this:

    # systemctl list-units | grep gravity
    gravity__gravitational.io__planet-master__0.1.87-1714.service          loaded active running
        Auto-generated service for the package
    gravity__gravitational.io__teleport__2.3.5.service                      loaded active running
        Auto-generated service for the package
  2. Shut down the teleport service:

    systemctl stop gravity__gravitational.io__teleport__2.3.5.service
  3. Shut down the planet-master service:

    systemctl stop gravity__gravitational.io__planet-master__0.1.87-1714.service

On a multi-node cluster, you’ll need to shut down gravity AND all gravity-site pods:

kubectl delete pods -n kube-system gravity-site-XXXXX

In both cases, you’ll need to restart gravity services:

systemctl start gravity__gravitational.io__planet-master__0.1.87-1714.service
systemctl start gravity__gravitational.io__teleport__2.3.5.service

GPU affinity setting reverts to default during upgrade

When upgrading Anaconda Enterprise from a version that supports the ability to reserve GPU nodes to a newer version (e.g., 5.2.x > 5.2.3), the nodeAffinity setting reverts to the default value, thus allowing CPU sessions and deployments to run on GPU nodes.


If you had commented out the nodeAffinity section of the Config map in your previous installation, you’ll need to do so again after completing the upgrade process. See Setting resource limits for more information.

Install and post-install problems

Failed installations

If an installation fails, you can view the failed logs as part of the support bundle in the failed installation UI.

After executing sudo gravity enter you can check /var/log/messages to troubleshoot a failed installation or these types of errors.

After executing sudo gravity enter you can run journalctl to look at logs to troubleshoot a failed installation or these types of errors:

journalctl -u gravity-23423lkqjfefqpfh2.service


Replace gravity-23423lkqjfefqpfh2.service with the name of your gravity service.

You may see messages in /var/log/messages related to errors such as “etcd cluster is misconfigured” and “etcd has no leader” from one of the installation jobs, particularly gravity-site. This usually indicates that etcd needs more compute power, needs more space or is on a slow disk.

Anaconda Enterprise is very sensitive to disk latency, so we usually recommend using a better disk for /var/lib/gravity on target machines and/or putting etcd data on a separate disk. For example, you can mount etcd under /var/lib/gravity/planet/etcd on the hosts.

After a failed installation, you can uninstall Anaconda Enterprise and start over with a fresh installation.

Failed on pulling gravitational/rbac

If the node refuses to install and fails on pulling gravitational/rbac, create a new directory TMPDIR before installing and provide write access to user 1000.

“Cannot continue” error during install

This bug is caused by a previous failure of a kernel module check or other preflight check and subsequent attempt to reinstall.

Stop the install, make sure the preflight check failure is resolved, and restart the install again.

Problems during post-install or post-upgrade steps

Post-install and post-upgrade steps run as Kubernetes jobs. When they finish running, the pods used to run them are not removed. These and other stopped pods can be found using:

kubectl get pods -A

The logs in each of these three pods will be helpful for diagnosing issues in the following steps:


Issues in this step


post-install UI


installation step


post-update steps

Post-install configuration doesn’t complete

After completing the post-install steps, clicking FINISH SETUP may not close the screen, and prevent you from continuing.

You can complete the process by running the following commands within gravity.

To determine the site name:

SITE_NAME=$(gravity status --output=json | jq '.cluster.token.site_domain' -r)

To complete the post-install process:

gravity --insecure site complete

Re-starting the post-install configuration

In order to reinitialize the post-install configuration UI—to regenerate temporary (self-signed) SSL certificates or reconfigure the platform based on your domain name—you must re-create and re-expose the service on a new port.

First, export the deployment’s resource manifest:

helm template --name anaconda-enterprise /var/lib/gravity/local/packages/unpacked/ -x /var/lib/gravity/local/packages/unpacked/ > wagon.yaml

Edit wagon.yaml, replacing image: ae-wagonwheel:5.X.X with image: leader.telekube.local:5000/ae-wagonwheel:5.X.X

Then recreate the ae-wagonwheel deployment using the updated YAML file:

kubectl create -f /var/lib/gravity/site/packages/unpacked/ -n kube-system

NOTE: Replace 5.X.X with your actual version number.

To ensure the deployment is running in the system namespace, execute sudo gravity enter and run:

kubectl get deploy -n kube-system

One of these should be ae-wagonwheel, the post-install configuration UI. To make this visible to the outside world, run:

kubectl expose deploy ae-wagonwheel --port=8000 --type=NodePort --name=post-install -n kube-system

This will run the UI on a new port, allocated by Kubernetes, under the name post-install.

To find out which port it is listening under, run:

kubectl get svc -n kube-system | grep post-install

Then navigate to http://<your domain>:<this port> to access the post-install UI.

Kernel parameters may be overwritten and cause networking errors

If networking starts to fail in Anaconda Enterprise, it may be because a kernel parameter related to networking was inadvertently overwritten.


On the master node running AE, run gravity status and verify that all kernel parameters are set correctly. If the Status for a particular parameter is degraded, follow the instructions here to reset the kernel parameter.

Removing collaborator from project with open session generates error

If you remove a collaborator from a project while they have a session open for that project, they might see a 500 Internal Server Error message.


Add the user as a collaborator to the project, have them stop their notebook session, then remove them as a collaborator. For more information, see how to share a project.

To prevent collaborators from seeing this error, ask them to close their running session before you remove them from the project.

AE auth pod throws OutOfMemory Error

If you see an exception similar to the following, Anaconda Enterprise has exceeded the maximum heap size for the JVM:

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "default task-248"
2018-08-29 23:13:26.327 UTC ERROR    XNIO001007: A channel event listener threw an exception: java.lang.OutOfMemoryError: Java heap space (default I/O-36) [org.xnio.listener]

Fetch changes behavior in Apache Zeppelin may not be obvious to new users

A Fetch changes notification appears, but the changes do not get applied to the editor. This is how Zeppelin works, but users unfamiliar with the editor may find it confusing.

If a collaborator makes changes to a notebook that’s also open by another user, the user needs to pull the changes that the collaborator made AND click the small reload arrows to refresh their notebook with the changes (see below).


Affected versions


Apache Zeppelin can’t locate conflicted files or non-Zeppelin notebook files

If you need to access files other than Apache Zeppelin notebooks within a project, you can use the %sh interpreter from within a Zeppelin notebook to work with files via bash commands, or use the Settings tab to change the default editor to Jupyter Notebooks or JupyterLab and use the file browser or terminal.

Affected versions


Create and Installer buttons are not visible on Channels page

When the Channels page is viewed initially, the Create and Installers buttons are not visible on the top right section of the screen. This prevents the user from creating channels or viewing a list of installers.


To make the Create and Installer buttons visible on the Channels page, perform one of the following steps:

  • Click on the top-level Channels navigation link again when viewing the Channels page

  • Click on a specific channel to view its detail page, then return to the Channels page

Affected versions


Updating a package from the Anaconda metapackage

When updating a package dependency of a project, if that dependency is part of the Anaconda metapackage the package will be installed once but a subsequent anaconda-project call will uninstall the upgraded package.


When updating a package dependency remove the anaconda metapackage from the list of dependencies at the same time add the new version of the dependency that you want to update.

Affected versions

5.1.0, 5.1.1, 5.1.2, 5.1.3

File size limit when uploading files

Unable to upload new files inside of a project that are larger than the current restrictions:

  • The limit of file uploads in JupyterLab is 15 MB

Affected versions

5.1.0, 5.1.1, 5.1.2, 5.1.3, 5.2.0, 5.2.1, 5.2.2, 5.2.3

IE 11 compatibility issue when using Bokeh in projects (including sample projects)

Bokeh plots and applications have had a number of issues with Internet Explorer 11, which typically result in the user seeing a blank screen.


Upgrade to the latest version of Bokeh available. On Anaconda 4.4 the latest is 0.12.7. On Anaconda 5.0 the latest version of Bokeh is 0.12.13. If you are still having issues, consult the Bokeh team or support.

Affected versions

5.1.0, 5.1.1, 5.1.2, 5.1.3

IE 11 compatibility issue when downloading custom Anaconda installers

Unable to download a custom Anaconda installer from the browser when using Internet Explorer 11 on Windows 7. Attempting to download a custom installer with this setup will result in an error that “This page can’t be displayed”.


Custom installers can be downloaded by refreshing the page with the error message, clicking the “Fix Connection Error” button, or using a different browser.

Affected versions

5.1.0, 5.1.1, 5.1.2, 5.1.3

Project names over 40 characters may prevent JupyterLab launch

If a project name is more than 40 characters long, launching the project in JupyterLab may fail.


Rename the project to a name less than 40 characters long and launch the project in JupyterLab again.

Affected versions

5.1.1, 5.1.2, 5.1.3

Long-running jobs may falsely report failure

If a job (such as an installer, parcel, or management pack build) runs for more than 10 minutes, the UI may falsely report that the job has failed. The apparent job failure occurs because the session/access token in the UI has expired.

However, the job will continue to run in the background, the job run history will indicate a status of “running job” or “finished job”, and the job logs will be accessible.


To prevent false reports of failed jobs from occurring in the UI, you can extend the access token lifespan (default: 10 minutes).

To extend the access token lifespan, log in to the Anaconda Enterprise Authentication Center, navigate to Realm Settings > Tokens, then increase the Access Token Lifespan to be at least as long as the jobs being run (e.g., 30 minutes).

Affected versions

5.1.0, 5.1.1, 5.1.2, 5.1.3

New Notebook not found on IE11

On Internet Explorer 11, creating a new Notebook in a Classic Notebook editing session may produce the error “404: Not Found”. This is an artifact of the way that Internet Explorer 11 locates files.


If you see this error, click “Back to project”, then click “Return to Session”. This refreshes the file list and allows IE11 to find the file. You should see the new notebook in the file list. Click on it to open the notebook.

Affected versions

5.0.4, 5.0.5

Disk pressure errors on AWS

If your Anaconda Enterprise instance is on Amazon Web Services (AWS), overloading the system with reads and writes to the directory /opt/anaconda can cause disk pressure errors, which may result in the following:

  • Slow project starts.

  • Project failures.

  • Slow deployment completions.

  • Deployment failures.

If you see these problems, check the logs to verify whether disk pressure is the cause:

  1. To list all nodes, run:

    kubectl get node
  2. Identify which node is experiencing issues, then run the following command against it, to view the log for that node:

    kubectl describe node <master-node-name>

If there is disk pressure, the log will display an error message similar to the following:



To relieve disk pressure, you can add disks to the instance by adding another Elastic Block Store (EBS) volume. If the disk pressure is being caused by a back up, you can move the backed up file somewhere else (e.g., to an NFS mount). See Backing up and restoring AE for more information.

To add disks to the instance by adding another Elastic Block Store (EBS) volume.

  1. Open the AWS console and add a new EBS volume provisioned to 3000 IOPS. A typical disk size is 500 GB.

  2. Attach the volume to your AE 5 master.

  3. To find your new disk’s name run fdisk -l. Our example disk’s name is /dev/nvme1n1. In the rest of the commands on this page, replace /dev/nvme1n1 with your disk’s name.

  4. Format the new disk: fdisk /dev/nvme1n1

    To create a new partition, at the first prompt press n and then the return key.

    Accept all default settings.

    To write the changes, press w and then the return key. This will take a few minutes.

  5. To find your new partition’s name, examine the output of the last command. If the name is not there, run fdisk -l again to find it.

    Our example partition’s name is /dev/nvme1n1p1. In the rest of the commands on this page, replace /dev/nvme1n1p1 with your partition’s name.

  6. Make a file system on the new partition: mkfs /dev/nvme1n1p1

  7. Make a temporary directory to capture the contents of /opt/anaconda: mkdir /opt/aetmp

  8. Mount the new partition to /opt/aetmp: mount /dev/nvme1n1p1 /opt/aetmp

  9. Shut down the Kubernetes system.

    Find the gravity services: systemctl list-units | grep gravity

    You will see output like this:

    # systemctl list-units | grep gravity
    gravity__gravitational.io__planet-master__0.1.87-1714.service          loaded active running
        Auto-generated service for the package
    gravity__gravitational.io__teleport__2.3.5.service                      loaded active running
        Auto-generated service for the package

    Shut down the teleport service: systemctl stop gravity__gravitational.io__teleport__2.3.5.service

    Shut down the planet-master service: systemctl stop gravity__gravitational.io__planet-master__0.1.87-1714.service

  10. Copy everything from /opt/anaconda to /opt/aetmp: rsync -vpoa /opt/anaconda/* /opt/aetmp

  11. Include the new disk at the /opt/anaconda mount point by adding this line to your file systems table at /etc/fstab:

    /dev/nvme1n1p1   /opt/anaconda   ext4    defaults        0 0

    Use mixed spaces and tabs in this pattern: /dev/nvme1n1p1<tab>/opt/anaconda<tab>ext4<tab>defaults<tab>0<space>0

  12. Move the old /opt/anaconda out of the way to /opt/anaconda-old: mv /opt/anaconda /opt/anaconda-old

    If you’re certain the rsync was successful, you may instead delete /opt/anaconda: rm -r /opt/anaconda

  13. Unmount the new disk from the /opt/aetmp mount point: umount /opt/aetmp

  14. Make a new /opt/anaconda directory: mkdir /opt/anaconda

  15. Mount all the disks defined in fstab: mount -a

  16. Restart the gravity services:

    systemctl start gravity__gravitational.io__planet-master__0.1.87-1714.service
    systemctl start gravity__gravitational.io__teleport__2.3.5.service

Disk pressure error during backup

If a disk pressure error occurs while backing up your configuration, the amount of data being backed up has likely exceeded the amount of space available to store the backup files. This triggers the Kubernetes eviction policy defined in the kubelet startup parameter and causes the backup to fail.

To check your eviction policy, run the following commands on the master node:

sudo gravity enter
systemctl status | grep "/usr/bin/kubelet"


Restart the backup process, and specify a location with sufficient space (e.g., an NFS mount) to store the backup files. See Backing up and restoring AE for more information.

General diagnostic and troubleshooting steps

Entering Anaconda Enterprise environment

To enter the Anaconda Enterprise environment and gain access to kubectl and other commands within Anaconda Enterprise, use the command:

sudo gravity enter

Moving files and data

Occasionally you may need to move files and data from the host machine to the Anaconda Enterprise environment. If so, there are two shared mounts to pass data back and forth between the two environments:

  • host: /opt/anaconda/ -> AE environment: /opt/anaconda/

  • host: /var/lib/gravity/planet/share -> AE environment: /ext/share

If data is written to either of the locations, that data will be available on both the host machine and within the Anaconda Enterprise environment


AWS Traffic needs to handle the public IPs and ports. You should either use a canonical security group with the proper ports opened or manually add the specific ports listed in Network Requirements.

Problems during air gap project migration

The command anaconda-project lock over-specifies the channel list resulting in a conda bug where it adds defaults from the internet to the list of channels.


Add to the .condarc: “default_channels”. This way, when conda adds “defaults” to the command it is adding the internal repo server and not the URLs.

  - our-internal
  - out-partners
  - rdkit
  - bioconda
  - defaults
  - r-channel

LDAP error in ap-auth

[LDAP: error code 12 - Unavailable Critical Extension]; remaining name 'dc=acme, dc=com'

This error can be caused when pagination is turned on. Pagination is a server side extension and is not supported by some LDAP servers, notably the Sun Directory server.

Session startup errors

If you need to troubleshoot session startup, you can use a terminal to view the session startup logs. When session startup begins the output of the anaconda-project prepare command is written to /opt/continuum/preparing, and when the command completes the log is moved to /opt/continuum/prepare.log.
